The new ROTOVIB is a development which adds a linear, vibratory movement of the pin shaft
relative to the destemmer cylinder.
A vibrator is mounted on the pin shaft and drive is fixed on rubber mountings. The resulting
longitudinal motion of the pin shaft is approximately 2 - 4mm at a frequency of 2300 oscillations per
minute. This additional energy causes a dispersion of the grapes inside the destemming cylinder
and allows the reduction of the speed of the pin shaft by approximately 50 - 60 %
Ripe grapes separate from the stem before being scraped off at the destemming cylinder. The
grape stems remain intact. The pin shaft speed can be adjusted to the degree of ripeness and the
type of grape. This has resulted in a significant increase in efficiency and enhancement in the
destemmer's range of application.
Another advantage of this design is the spring-supported (floating) mounting of the pin shaft, which
prevents pressure from being exerted on the grapes.
Damage by foreign objects is also minimized.

ROTOVIB achieves much higher efficiency for gentle grape processing than destemmers using rubber paddles on the pin shaft. The destemming cylinder consists of impact-resistant plastic segments with no sharp edges.
The gentle destemming process preserves the integrity of the stems and discharges them undamaged. The destemming cylinder can be operated clockwise and counter clockwise. The new ROTOVIB is the prerequisite for high-quality grapes.
